Zudem kann es zu unerwünschten Formtoleranzen und Unrundheiten der Bandrollen kommen. Zur Kompensation der unterschiedlichen Bandzüge bzw. Bahnspannungen der einzelnen Metallstreifen und somit zur Verbesserung der Formtoleranzen werden bereits erfolgreich Kontaktwalzeneinheiten verwendet, die für jeden Metallstreifen beispielsweise einen separaten Walzenkörper aufweisen können, sodass für jeden Metallstreifen eine individuelle Einstellung der Kontaktkraft, mit der der jeweilige Walzenkörper an der zugeordneten Bandrolle anliegt, ermöglicht wird. Gleichwohl besteht der Wunsch, die Gleichförmigkeit der einzelnen gewickelten Bandrollen weiter zu verbessern.In addition, undesired shape tolerances and out-of-roundness of the coils can occur. To compensate for the different strip tensions or web tensions of the individual metal strips and thus to improve the shape tolerances, contact roller units are already being used successfully, which can have a separate roller body for each metal strip, for example, so that the contact force with which the respective roller body can be individually adjusted for each metal strip the associated roll of tape is applied, is made possible. However, there is a desire to further improve the uniformity of the individual wound rolls of tape.

- ein Gestell,
- einen Träger zum Tragen einer Mehrzahl von Wickelhülsen, wobei der Träger an dem Gestell befestigt ist, sodass der Träger relativ zu dem Gestell nicht drehbar ist, und

- a carrier for supporting a plurality of cores, the carrier being fixed to the frame such that the carrier is non-rotatable relative to the frame, and
- a plurality of electric motors, by means of which at least two of the winding cores of the plurality of winding cores can be driven separately.
Die vorgeschlagene Wickelstation ist insbesondere in Zusammenhang mit einer Schneidmaschine, beispielsweise nach Art einer Bandschneidmaschine oder Folienschneidmaschine, verwendbar. Mittels solcher Schneidmaschinen ist ein Metallband bzw. eine Metallfolie in einer Längsrichtung des Metallbandes bzw. der Metallfolie schneidbar, sodass aus dem Metallband bzw. der Metallfolie eine Mehrzahl von Metallstreifen gebildet wird. Das Metallband bzw. die Metallfolie sowie die einzelnen Metallstreifen bestehen bevorzugt aus Aluminium, einer Aluminiumlegierung oder einer Nichteisen-Legierung. Bei dem Metallband handelt es sich insbesondere um Aluminiumband, bei der Metallfolie insbesondere um Aluminiumfolie und/oder der Mehrzahl von Metallstreifen um eine Mehrzahl von Aluminiumstreifen. Das Metallband bzw. die Metallfolie weist eine Metallbandbreite bzw. eine Metallfolienbreite von insbesondere 400 mm (Millimeter) bis 2.500 mm und/oder eine Metallbanddicke bzw. Metallfoliendicke von insbesondere 0,01 mm bis 0,5 mm auf. Die einzelnen geschnittenen Metallstreifen weisen insbesondere eine Streifenbreite von 10 mm bis 500 mm, bevorzugt 10 mm bis 250 mm und besonders bevorzugt 10 mm bis 50 mm, und/oder einer Streifendicke von 0,01 mm bis 0,5 mm auf. Bei einer besonderen Ausführungsform weist die Streifenbreite (circa) 20 mm auf.The proposed winding station can be used in particular in connection with a cutting machine, for example in the manner of a tape cutting machine or foil cutting machine. A metal strip or a metal foil can be cut by means of such cutting machines in a longitudinal direction of the metal strip or the metal foil, so that a plurality of metal strips is formed from the metal strip or the metal foil. The metal band or the metal foil and the individual metal strips are preferably made of aluminum, an aluminum alloy or a non-ferrous alloy. The metal strip is in particular aluminum strip, the metal foil is in particular aluminum foil and/or the plurality of metal strips is a plurality of aluminum strips. The metal strip or the metal foil has a metal strip width or a metal foil width of in particular 400 mm (millimeters) to 2,500 mm and/or a metal strip thickness or metal foil thickness of in particular 0.01 mm to 0.5 mm. The individual cut metal strips have in particular a strip width of 10 mm to 500 mm, preferably 10 mm to 250 mm and particularly preferably 10 mm to 50 mm, and/or a strip thickness from 0.01 mm to 0.5 mm. In a particular embodiment, the strip width is (approximately) 20 mm.
Das Metallband bzw. die Metallfolie wird insbesondere mittels einer Abwickelstation von einem Coil abgewickelt und einer Schneidstation der Schneidmaschine zugeführt. Die Schneidstation schneidet das Metallband bzw. die Metallfolie in der Längsrichtung des Metallbandes bzw. der Metallfolie, sodass aus dem Metallband bzw. der Metallfolie eine Mehrzahl von Metallstreifen gebildet wird. Mittels der Schneidstation können beispielsweise 2 bis 100 parallele Metallstreifen geschnitten werden. Die Mehrzahl von Metallstreifen wird anschließend zumindest einer Wickelstation zugeführt, mittels der jeder Metallstreifen zu einer Bandrolle gewickelt wird. Insbesondere kann eine Mehrzahl von ersten Metallstreifen einer ersten Wickelstation und eine Mehrzahl von zweiten Metallstreifen einer zweiten Wickelstation der Schneidmaschine zugeführt werden. Die ersten Metallstreifen und zweiten Metallstreifen verlaufen vor ihrer Trennung bevorzugt wechselweise parallel nebeneinander. Dies bedeutet mit anderen Worten, dass vor der Trennung abwechselnd ein erster Metallstreifen und ein zweiter Metallstreifen nebeneinander verlaufen. Durch die Zuführung der Mehrzahl erster Metallstreifen zu der ersten Wickelstation und der Mehrzahl zweiter Metallstreifen zu der zweiten Wickelstation kann mit der ersten Wickelstation und der zweiten Wickelstation jeweils eine Mehrzahl von parallel zueinander angeordneten Bandrollen gewickelt werden, wobei die einzelnen Bandrollen beim Aufwickeln zueinander einen Abstand aufweisen. Der Abstand entspricht dabei insbesondere der Streifenbreite des Metallstreifens, der vor der Trennung zwischen den Metallstreifen benachbarter Bandrollen verlief. Der Abstand kann jedoch auch größer oder kleiner sein. Durch den Abstand zwischen den einzelnen Bandrollen wird verhindert, dass sich die einzelnen Bandrollen beim Aufwickeln gegenseitig beeinflussen. So zum Beispiel kann verhindert werden, dass sich die Metallstreifen benachbarter Bandrollen beim Aufwickeln berühren, überlappen und/oder gegenseitig deformieren.The metal strip or the metal foil is unwound from a coil in particular by means of an unwinding station and fed to a cutting station of the cutting machine. The cutting station cuts the metal strip or the metal foil in the longitudinal direction of the metal strip or the metal foil, so that a plurality of metal strips is formed from the metal strip or the metal foil. For example, 2 to 100 parallel metal strips can be cut by means of the cutting station. The plurality of metal strips is then fed to at least one winding station, by means of which each metal strip is wound into a roll of tape. In particular, a plurality of first metal strips can be fed to a first winding station and a plurality of second metal strips can be fed to a second winding station of the cutting machine. Before they are separated, the first metal strips and second metal strips preferably run alternately parallel next to one another. In other words, this means that prior to the separation, a first metal strip and a second metal strip alternately run side by side. By feeding the plurality of first metal strips to the first winding station and the plurality of second metal strips to the second winding station, a plurality of rolls of tape arranged parallel to one another can be wound with the first winding station and the second winding station, with the individual rolls of tape being at a distance from one another during winding . In this case, the distance corresponds in particular to the strip width of the metal strip that ran between the metal strips of adjacent rolls of tape before the separation. However, the distance can also be larger or smaller. The distance between the individual rolls of tape prevents the individual rolls of tape from influencing each other during winding. For example, the metal strips of adjacent rolls of tape can be prevented from touching, overlapping and/or deforming one another during winding.
Die Wickelstation weist ein Gestell auf, das insbesondere zumindest teilweise aus Metall besteht. Weiterhin kann das Gestell Metallprofile und/oder Metallplatten umfassen. Das Gestell ist fest oder bewegbar auf einem Boden oder alternativ fest oder bewegbar an einem Maschinengestell der Schneidmaschine angeordnet.The winding station has a frame which consists in particular at least partially of metal. Furthermore, the frame can comprise metal profiles and/or metal plates. The frame is fixed or movable on a floor or alternatively fixed or movable on a machine frame of the cutting machine.
Weiterhin umfasst die Wickelstation einen, insbesondere horizontal angeordneten, Träger zum Aufnehmen einer Mehrzahl von Wickelhülsen, wobei der Träger an dem Gestell befestigt ist. Der Träger besteht bevorzugt ebenfalls zumindest teilweise aus Metall. Die Befestigung des Trägers an dem Gestell erfolgt insbesondere fest, sodass der Träger relativ zu dem Gestell nicht drehbar bzw. rotierbar ist.

Auf jeder Wickelhülse der Mehrzahl von Wickelhülsen ist ein (einzelner) Metallstreifen zu einer Bandrolle oder eine Mehrzahl der Metallstreifen zu einer Mehrzahl von Bandrollen aufwickelbar. Die Bandrolle kann nach ihrer Fertigstellung insbesondere einen Bandrollendurchmesser von 100 mm bis 2.000 mm, bevorzugt 160 mm bis 1.800 mm aufweisen.The individual winding sleeves of the plurality of winding sleeves are also in particular tubular and/or consist at least partially of plastic or a metal such as aluminum or steel.

Die Wickelstation umfasst eine Mehrzahl von Elektromotoren, die auf dem insbesondere horizontal angeordneten Träger installiert sein können. Mittels der Elektromotoren sind zumindest zwei der Wickelhülsen der Mehrzahl von Wickelhülsen separat antreibbar. Dies bedeutet, dass zumindest zwei Wickelhülsen unabhängig voneinander, getrennt und/oder individuell, d. h. beispielsweise mit einem eigenen Drehmoment und/oder mit einer eigenen Drehzahl, antreibbar bzw. relativ zu dem Träger um eine Rotationsachse rotierbar sind. Die Wickelstation kann hierzu beispielsweise 2 bis 50 Elektromotoren umfassen. Die einzelnen Wickelhülsen sind insbesondere mit einer Drehzahl von bis zu 1000 U/min (Umdrehung pro Minute), insbesondere 0 U/min bis 600 U/min antreibbar. Weiterhin kann die Wickelstation auch derart ausgebildet sein, dass mit jedem einzelnen Elektromotor eine einzelne Wickelhülse separat antreibbar ist und/oder dass jede der Wickelhülsen mit zumindest einem Elektromotor separat antreibbar ist. Dies bedeutet, dass jede Wickelhülse getrennt bzw. individuell, d. h. beispielsweise mit einem eigenen Drehmoment und/oder mit einer eigenen Drehzahl, antreibbar bzw. relativ zu dem Träger um eine Rotationsachse rotierbar ist. Insbesondere bei sehr schmal geschnittenen Bandrollen (z. B. bei Streifenbreiten von weniger als 50 mm) kann allerdings auch die Möglichkeit bestehen, dass, beispielsweise aufgrund baulicher Gegebenheiten, auch mit zumindest einem Elektromotor eine (einzelne) Wickelhülse für eine Mehrzahl von Bandrollen, beispielsweise zwei oder drei Bandrollen, mit einer separaten Drehzahl und/oder einem separaten Drehmoment antreibbar ist. Umgekehrt kann auch, beispielsweise bei breiten Wickelhülsen (z. B. bei Wickelhülsen mit einer Wickelhülsenbreite von mehr als 50 mm), mit einer Mehrzahl von Elektromotoren, beispielsweise zwei Elektromotoren, eine (einzige) Wickelhülse antreibbar sein. Zudem kann auch vorgesehen sein, dass ein Teil der Wickelhülsen gemeinsam mit einem Elektromotor antreibbar sind. Weiterhin kann die Wickelstation zumindest eine Steuerung aufweisen, die beispielsweise zumindest einen Mikrocontroller und/oder einen Datenspeicher umfasst, mittels der die Elektromotoren getrennt voneinander oder gruppenweise steuerbar sind. Dies bedeutet insbesondere, dass jeder Elektromotor oder eine Mehrzahl von Elektromotoren. insbesondere in Abhängigkeit des Bandrollendurchmessers der jeweiligen Bandrolle oder der jeweiligen Bandrollen, mit unterschiedlichen Drehzahlen und/oder mit unterschiedlichen Drehmomenten betrieben werden kann. Der Bandrollendurchmesser der einzelnen Bandrollen kann hierfür beispielsweise mittels zumindest eines Sensors und/oder eines mathematischen Modells bestimmt werden. Jeder Elektromotor kann zudem beispielsweise eine Leistung von 1 kW (Kilowatt) bis 10 kW, bevorzugt 3 kW bis 5 kW und besonders bevorzugt 4 kW aufweisen. Bei den Elektromotoren handelt es sich insbesondere um sogenannter "Rotary Table"-Motoren oder Spindelmotoren. Durch den getrennten bzw. separaten Elektromotor der einzelnen Wickelhülsen können durch die einzelnen Elektromotoren in Abhängigkeit des Bandrollendurchmessers der einzelnen Bandrollen individuelle Drehmomente erzeugt werden, sodass ein konstanter Bandzug (in N) (Newton)) bzw. eine konstante (spezifische) Bahnspannung (in N/mm2 (Newton pro Quadratmillimeter)) in den einzelnen Metallstreifen erzeugbar ist. Hiermit sind Bandrollen mit einer größeren Gleichförmigkeit herstellbar.The winding station comprises a plurality of electric motors, which can be installed on the carrier, which is arranged in particular horizontally. At least two of the winding cores of the plurality of winding cores can be driven separately by means of the electric motors. This means that at least two winding sleeves can be driven independently of one another, separately and/or individually, ie for example with their own torque and/or with their own speed, or can be rotated relative to the carrier about an axis of rotation. For this purpose, the winding station can comprise, for example, 2 to 50 electric motors. The individual winding sleeves can be driven in particular at a speed of up to 1000 rpm (revolutions per minute), in particular 0 rpm to 600 rpm. Furthermore, the winding station can also be designed in such a way that a single winding sleeve can be driven separately with each individual electric motor and/or that each of the winding sleeves is equipped with at least one electric motor can be driven separately. This means that each winding sleeve can be driven separately or individually, ie for example with its own torque and/or at its own speed, or can be rotated relative to the carrier about an axis of rotation. However, particularly in the case of very narrow rolls of tape (e.g. strip widths of less than 50 mm), there may also be the possibility, for example due to structural conditions, that a (single) winding core for a plurality of rolls of tape, for example two or three tape rollers, can be driven at a separate speed and/or a separate torque. Conversely, for example in the case of wide winding cores (e.g. in the case of winding cores with a winding core width of more than 50 mm), a (single) winding core can be driven with a plurality of electric motors, for example two electric motors. In addition, it can also be provided that some of the winding sleeves can be driven together with an electric motor. Furthermore, the winding station can have at least one controller, which includes, for example, at least one microcontroller and/or a data memory, by means of which the electric motors can be controlled separately from one another or in groups. This means in particular that each electric motor or a plurality of electric motors. can be operated at different speeds and/or with different torques, in particular as a function of the tape roll diameter of the respective tape roll or the respective tape rolls. For this purpose, the reel diameter of the individual reels can be determined, for example, by means of at least one sensor and/or a mathematical model. In addition, each electric motor can, for example, have an output of 1 kW (kilowatt) to 10 kW, preferably 3 kW to 5 kW and particularly preferably 4 kW. The electric motors are, in particular, so-called “rotary table” motors or spindle motors. Through the separate or separate electric motor of the individual cores can the individual electric motors generate individual torques depending on the roll diameter of the individual rolls, so that a constant strip tension (in N) (Newton)) or a constant (specific) web tension (in N/mm 2 (Newton per square millimeter)) in the individual Metal strip can be generated. This allows rolls of tape to be produced with greater uniformity.
Weiterhin kann die Mehrzahl von Elektromotoren an dem Träger befestigt sein. Die Befestigung kann dabei reibschlüssig, formschlüssig oder stoffschlüssig erfolgen.Furthermore, the plurality of electric motors can be fixed to the carrier. The attachment can be frictional, form-fitting or material-to-material.
Zudem kann jeder Elektromotor der Mehrzahl von Elektromotoren ringförmig ausgebildet sein.

Darüber hinaus kann jeder Elektromotor der Mehrzahl von Elektromotoren eine Breite aufweisen, die maximal doppelt so groß ist, wie eine Streifenbreite eines einzelnen Metallstreifens der Mehrzahl von Metallstreifen. Bei einer Streifenbreite von z. B. 20 mm und einer Schnittbreite von z. B. 20 mm kann jede Wickelhülse beispielsweise eine Wickelhülsenbreite von 40 mm und jeder Elektromotor beispielsweise eine Breite von 40 mm aufweisen.In addition, each electric motor of the plurality of electric motors can have a width that is at most twice as large as a strip width of an individual metal strip of the plurality of metal strips.

Des Weiteren kann die Mehrzahl von Elektromotoren zumindest eine Anschlussleitung aufweisen, wobei die zumindest eine Anschlussleitung zumindest teilweise durch den Träger verläuft. Bevorzugt weist jeder Elektromotor zumindest eine Anschlussleitung auf. Bei der zumindest einen Anschlussleitung handelt es sich insbesondere um eine Steuerleitung zur Übertragung von Steuersignalen und/oder um eine Stromleitung zur Übertragung von elektrischer Energie.Furthermore, the plurality of electric motors can have at least one connection line, the at least one connection line running at least partially through the carrier. Each electric motor preferably has at least one connection line. With the at least one connection line it is in particular a control line for the transmission of control signals and/or a power line for the transmission of electrical energy.
Zudem kann jede Wickelhülse der Mehrzahl von Wickelhülsen an einem Elektromotor der Mehrzahl von Elektromotoren befestigt sein. Insbesondere kann jede Wickelhülse der Mehrzahl von Wickelhülsen an einem einzelnen Elektromotor der Mehrzahl von Elektromotoren befestigt sein. Die Wickelhülsen sind dabei insbesondere an dem (ringförmigen) Rotor des Elektromotors befestigt. Die Befestigung kann beispielsweise reibschlüssig und/oder formschlüssig erfolgen.In addition, each winding sleeve of the plurality of winding sleeves can be attached to an electric motor of the plurality of electric motors. In particular, each winding sleeve of the plurality of winding sleeves can be attached to a single electric motor of the plurality of electric motors. The winding sleeves are in particular attached to the (ring-shaped) rotor of the electric motor. The attachment can, for example, be frictional and/or form-fitting.
Weiterhin kann jede Wickelhülse der Mehrzahl von Wickelhülsen mit einer separaten Klemmvorrichtung an einem Elektromotor der Mehrzahl von Elektromotoren befestigt sein. Insbesondere kann jede Wickelhülse der Mehrzahl von Wickelhülsen mit einer separaten Klemmvorrichtung an einem einzigen Elektromotor der Mehrzahl von Elektromotoren befestigt sein. Die Klemmvorrichtung kann beispielsweise nach Art zumindest eines Stempels ausgebildet sein, der insbesondere begrenzt in einer radialen Richtung verstellbar ist. Der zumindest eine Stempel kann beispielsweise mittels zumindest einer Feder vorgespannt und/oder mittels zumindest eines Aktors verstellbar sein.Furthermore, each winding sleeve of the plurality of winding sleeves can be attached to an electric motor of the plurality of electric motors with a separate clamping device. In particular, each winding sleeve of the plurality of winding sleeves can be attached to a single electric motor of the plurality of electric motors with a separate clamping device.

Hierzu werden die einzelnen Elektromotoren insbesondere durch zumindest eine Steuerung derart gesteuert, dass diese in Abhängigkeit des Bandrollendurchmessers der einzelnen Bandrollen ein Drehmoment erzeugen, aus dem in allen den einzelnen Bandrollen zugeführten Metallstreifen der Mehrzahl von Metallstreifen ein (im Wesentlichen) konstanter Bandzug bzw. eine (im Wesentlichen) konstante Bahnspannung resultiert. Hierzu kann der Bandrollendurchmesser der einzelnen Bandrollen insbesondere mit zumindest einem Sensor kontinuierlich oder diskontinuierlich gemessen werden, der insbesondere datenleitend mit der zumindest einer Steuerung verbunden ist. Weiterhin kann der Bandrollendurchmesser der einzelnen Bandrollen auch durch ein mathematisches Modell bestimmt werden.For this purpose, the individual electric motors are controlled in particular by at least one controller in such a way that they generate a torque as a function of the coil diameter of the individual coils, from which a (substantially) constant coil tension or a ( essentially) constant web tension results.
